CVE-2023-54034

The CVE-2023-54034 issue affects the Linux kernel iommufd path where vfio_iommu_type1_info is copied to user space. The root cause is a missing zero initialization: most of the struct is copied with copy_from_user(), but minsz is smaller than the struct by 8 bytes, leaving the padding uninitializ...

CVE-2025-68358

CVE-2025-68358 (Linux kernel, btrfs) : A race condition was fixed in btrfs_clear_space_info_full() that updated bitfield members (full, chunk_alloc, flush) without holding the space_info lock, risking corruption of adjacent fields due to non-atomic read-modify-write sequences on bitfields. The fi...

CVE-2025-68356 gfs2: Prevent recursive memory reclaim

In the Linux kernel, the following vulnerability has been resolved: gfs2: Prevent recursive memory reclaim Function newinode returns a new inode with inode-imapping-gfpmask set to GFPHIGHUSERMOVABLE. This value includes the GFPFS flag, so allocations in that address space can recurse into...
